On April 17, 2026, the Lake Mashu Safety Prayer Festival was held at Lake Mashu Kamuy Terrace, and at the same time, the drive course connecting Lake Mashu First Observatory and Mt. Io, known as the Mashu Lake Mount Io Sky Road, was opened 🚙🐾
At Lake Mashu Kamuy Terrace, flags, as shown in the photos, are also on sale 🚩
The season has arrived to enjoy Lake Mashu visible from the Third Observatory ✨ We invite you to visit us at least once.
